Table 2. Multivariable mixed effects model for choice between O-ASD and TC-ASD.

This table depicts the results of a single multivariate mixed effect model calculating the probability of choosing O-ASD over TC-ASD over the study period. Odds ratios greater than 1 represent a preference for O-ASD, and those less than 1 represent a preference for TC-ASD.
